Title:
BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/107067
Kind Code:
A1
Abstract:
In a normal condition, a brake liquid pressure generated by a slave cylinder (23) which operates according to the operation of a brake pedal (12) is supplied to wheel cylinders (16, 17; 20, 21) to perform braking, and when the slave cylinder (23) fails, a brake liquid pressure generated by a backup master cylinder (11) which operates according to the operation of the brake pedal (12) is supplied to the wheel cylinders (16, 17; 20, 21) to perform braking. In the latter case, the brake liquid is supplied to the wheel cylinders (16, 17; 20, 21) from a pump (64) before the driver depresses the brake pedal (12) to cause the brake liquid to be supplied from the master cylinder (11) to the wheel cylinders (16, 17; 20, 21). The configuration enables, without an increase in the stroke of the brake pedal (12), a required amount of the brake liquid to be supplied to the wheel cylinders (16, 17; 20, 21) to obtain a sufficient braking force.
